BOMB-CARRYING am @man UNDER THE Ac'r oF Manen 3, 188e, 22 STAT. L.,625.)

To all whom t may concern:

in the United States, without payment of any royalty thereon.

This invention relates to a bomb carrying gear for airplane bombs.

It is an important object of this invention to provide a simple, strongand light carrying gear for bombs so designed that the bomb is hung froma point above and `to one side of a bearing .for the sidevof the bomb,whereby the weight of the bomb will cause the side thereof to bearagainst the bearing and so prevent any vibration of the bomb whiletheairplane is in flight. The above faces in oppositedirections and sobalancel described arrangement does not in any way interfere with therelease of the bomb.

It is a further object of this invention to provide a mainsupporting ribon which two bombs may be hung and four bearing surfaces forthe sides ofthe bombs, two of said surfaces being located below and to one side with-respect to said rib, the other two of said surfaces being located belowand on the op-v posite side with. respect to the said rib, whereby thesides of the bombs, due to their own weight, bear against said bearingsureach other.

It is a further object of this invention to provide a truss support forthe said bearing surfaces.

It is a further object of this invention to provide a supporting rib onwhich two bombs may be hung and which is shaped substantially like aninverted V. The bombs are so hung with relation to this rib that thepull due tothe weight of the bombs is substantially parallel to therespective legs of said inverted V-shaped rib. This gives an extremelysti and rigid support, with a minimum of weight. l

Other objects and advantages will appear as the description proceeds.

In the drawings illustrating one embodiment of my inventiqn, Figure 1 isa side view of my bomb carrying gear.

Fig. 2 is an end view of the same.

Fig. 3 is a section on the line 3-3 of Fig. 2.

` Fig. 4 is a view partly in section of the releasing mechanism.

Figs. 5 and 6 are sectional views of the releasing mechanism, showingsuccessive stages of operation.

Fig. 7 is a perspective view ofthe sup- `porting rib and associatedparts.

F1g. 8 is a section of the same taken on the line 8-8 of Fig. 3.

Fig. 9. is a section of the same taken on the line 9 9 of Fig. 3.

The bomb carrying gear comprises a pair of horizontally extendingsupports, extending transversely with respect to the path of theairplane. These supports are substantially parallel to one another, theforward one being indicated at l and the rear one at 2.

Thesevsupports are stream lined to minimize air resistance.

The supports l and 2 are supported from beams 3, suitably attached tothe body or plane 4 of the airplane.

A pair of substantially U-shaped brackets i 5 and 6 supported by bolts 7from the front support l inclose between them the end of the mainsupporting rib 8, which is shaped like an inverted V. The rear end ofthe rib 8 is supported from the support 2 by precisely similar means.The brackets 5 and 6 and the end of the rib 8 are bonded together bybeing dip brazed.

A pair vof arcuately shaped hangers 9 and l0 are positioned in suitalbleapertures through each ofthe legs of the rib 8 and are rigidly heldinposition by cotter pins 11, and by dip brazing. The parts 5, 6 and 9may be dip brazed by the same operation.

The rib 8 is provided with a pair of longi-l tuating plate 13, providedwith an outwardly bent trigger engaging end 14, is attached to a secondsliding plate 15, the two plates being connected together by lugs 14,said lugs passing through the slot 12 and being formed as a part of theplate 15, and held in engagement rwith slide 13 by cotter pins. Each of'the slides 15 has attached thereto a spring 16, the other end isattached to a pin 17 fastened to the rib 8, to keep the slides 13 and l5to the right, as shown in Fig. l. Each of the slides 15 has attached atits other end an actuating rod 18, controlled by levers 19 and 20, whichin turn are controlled by manual operating means, not shown.

The front bearin for the bomb will now be described. Thisgbearingcomprises vertically disposed bearing surfaces 21 and 22 preferably madeintegral with a connecting piece 23. These bearing surfaces are sup'ported bya, V shaped element 24, which is attached to the support 1 bybolts 25, and which, at its apex is attached to the connecting piece 23.A compression element 26 is positioned between the apex of the V shapedelement 24 and the support 1 to complete the truss support for thebearing surfaces. An additional brace 27, engages with the bearingsurfaces 21 and 22. A precisely similar set of bearing surfaces andsupporting truss are provided toward the rear end of the bomb carryinggear, a's shown in Fig. 1. |The two trusses may be braced apart by theelement 28.

It should be noted that the bearing surfaces 21 and 22 are located belowand to one side with respect tothe rib 8.

The means, for attaching the bomb to the rib 8 will now be described.This connecting means or hanger comprises an elongated body element 29,made by bending a sheet of metal into substantially U-shaped form, thebight of the Uibeing indicated at 30.

The metal forming the ends of the element 29 has its upper partsfastened together as indicated at 31 and 32. Apertures 33 and 34 arepunched through the respective-portions 31 and 32. It should be notedthat these said apertures are spaced unequally from the ends of theelement 29.`

These said apertures are adapted to engage over the ends of the arcuateelements 9 and 10. It should be noted that the arcuate elements 9 and 10are also correspondingly and unequally spaced from the respective endsof the ri=b 8, being so arranged however that if the element 29 isengaged with the arcuate elements 9 and 10 right side up, the apertures33 and 3.4 will properly t over said elements 9 and 10, but ifelement 29is attemptedto be engaged on elements 9 and 10 wrong end to the saidapertures will not engage over said elements 9 and 10, and so theimproper mounting of the ele- 43 attached to the bomb. It rwill beapparent that the heavy weight of the bomb acting on the lever hooks 35and 36, will tend to move the up er arms of said hooks to the left, andwil consequently tend to move bar 4l y to the left.

A locking sear 44 is pivoted to the bar 41 at 45 and is normally urgeddownwardly by spring 46 bearing against itl and against an upper edge ofthe bar 41. The sear 44 is provided with a shoulder 47 that normally isengaged over an edge of a stop 48 rigidly mounted to the hanger 29. Whenthe parts are engaged as in Fig. 4 it is apparent that the bombs will beeffectively held against release.

A trigger 49 is pivoted to the hanger 29 at 50, is provided with a camface 51 that bears against the lower edge of the sear 44, and is furtherprovided with a notch 52, which overhangs the end 53 of the sear 44 andacts as a safety catch in case of failure of spring 46. The trigger 49is urged to the left by a spring 54. The described parts are soproportioned and shaped that when the trigger 49 is moved to the right,notchf 52 is first moved from the path of the end 53 of the sear, afterwhich the cam surface 51 lifts the sear 44 from engagement with the stop48, whereupon the bar 41 is released and moves to the left to releasethe bomb,

a sequence of operation clearly shown in Figs. 5 and .6.

The trigger 49 is actuated through the already described lever 20, rod18, slide 14 and lug 15, Figs. 1 and 3, or it may be actuated by a wireor cable fastened thereto in the aperture 49.

It should be understood that each rib 8 carries two hangers 29, as shownin Fig. 2

and so supports two bombs.

The hanger 29 and associated release mechanism forms the subject of aseparate application, Serial No. 302,585, filed June 7,

While I have illustrated a particular embodiment of my invention itShould be understood that it may be carried out in other ways as definedwithin the scope of the following claims.
